reactjs - React Native 运行保持在 IDLE 状态

Question

这是我第一次在 Ubuntu 18.04 LTS 上设置 React Native。我已完成设置，并尝试使用 react-native run-android 命令在设备上运行该应用程序。这是我在终端中得到的输出，

ron@lenovo:~/react/app$ react-native run-android
Scanning folders for symlinks in /home/ron/react/app/node_modules (9ms)
JS server already running.
Building and installing the app on the device (cd android && ./gradlew installDebug)...
Starting a Gradle Daemon, 1 busy Daemon could not be reused, use --status for details
NDK is missing a "platforms" directory.
If you are using NDK, verify the ndk.dir is set to a valid NDK directory.  It is currently set to /home/ron/Android/Sdk/ndk-bundle.
If you are not using NDK, unset the NDK variable from ANDROID_NDK_HOME or local.properties to remove this warning.

File /home/ron/.android/repositories.cfg could not be loaded.
Checking the license for package Android SDK Build-Tools 26.0.3 in /home/ron/Android/Sdk/licenses
License for package Android SDK Build-Tools 26.0.3 accepted.
Preparing "Install Android SDK Build-Tools 26.0.3 (revision: 26.0.3)".
<=============> 100% CONFIGURING

它永远停留在这个 IDLE 位置。修复或此问题是什么？

Answer 1

解决方案是安装 Android SDK rev. 26.0.3。您可以从 Android Studio 的 SDK Manager 菜单中的 File > Settings 安装它。希望这会有所帮助。
